So Im facing some weird problems with my new built. i recently replaced my motherboard due to some power issues, but now im facing heating issues. Whenever i launch a game, my motherboard heats and reaches 60-63 degrees also my cpu and gpu heats up. while my MB is 63 degrees my cpu is at 59 and gpu at 54 degrees. I recently (like 2 days ago i replaced my thermal heat sink paste) But still no use. Can't figure what the issue is.

My specs :

Asus H170M plus
i5 6500 processor
gtx 1050
12gb ram
550W PSU.

But after closing all the applications the temperature sets of to 35-38 degrees. But it heats abnormally while gaming. I also faced CPU going to sleep while playing heavy games. Can it be due to the heat? Please i need some help.

Thanks in advance.

So with fan blowing at mobo, you still had those freezes? In this case, I'm tempted to assume it's bad VRM, as it could cause both your problems. Obviously, it can be something else, but personally my next step would be to test mobo at comp shop - however as problem appears randomly, it can be hard to catch it.

I get it but when i play some heavy games such as fifa 18 and cod it heats up and monitor shuts off and cpu goes to sleep mode, i mean the LED light in cpu near power button goes off and on, i assume its sleep mode. Can it be because of Heat?

Also its been like 6 months since i built my pc. For the past six months it was fine and there was no rise in temperature levels. But suddenly since when i replaced and got a new MB im facing these issues. Can it be a cpu fan fault or i dont know..

See the temp on storage? That tells me, it is quite hot inside your case. How many case fans you have, and how they are set up?

The freezing problem could be caused by bad VRM on motherboard. However, 61 deg is not a temp at which VRM should be overheating, so it may just be faulty motherboard. CPU temps are good, so there is no reason to suspect cpu fan (esp if you have stock cooler, then this temp is 100% normal).

And i got one case fan which is set up at the backside of the case.

But now i've been playing for some time. My motherboard temperature seems to be constant but the cpu temperature are varying a lot. One time its like 35 degree the next time its like 44 then 48 then again 38 or in 30's. This happened when i just turned my pc on. Not even under load. But now my MB temperature seems to be constant. But sometime both MB and CPU heats together. But mostly its only CPU. What exactly maybe going wrong with my PC?



 


So just one fan, I assume it is set to exhaust. That is not much. While it should be enough for a basic setup like yours (a mid rang non OCed CPU and low range GPU), it may be good to add more case fans.
Rapid temp changes are perfectly normal with CPU. Even if you don't run any programs at all, Windows itself still runs a lot of processes in the background, using CPU. MB temp on the other hand, is supposed to be constant, as it works all time at same level. If it raises up, it is more due to increase of average temp inside case mostly, therefore it usually rises slowly but also it takes more time to get back to lower temps. Especially in a setup with just one case fan.

All right. Thanks for the help. But one final question, As i told earlier that my PC tends to go off (or sleep mode) is it all because of the case fan as you mentioned? Because i haven't faced such an issue for past 5 months. But recently i changed my pc to my downstair room. So all in the mind, all those temperature rise and going into sleep mode thing was due to ventilation?

Is there anything i can do to solve this? Might there be any fault in the motherboard like VRM issues? What should i do next?
Thanks in advance.
 
It's not a sleep mode - sleep mode can't turn on on it's own, unless you set it so in Windows, but then it only happens when computer is idle and doing nothing for set amount of time - which is not what happens to you.
It is hard to say, what causes that effect. Because it could be anything - from a purely software problem to a failing hardware component. Your description of the problem is not precise enough to put any diagnose. But yes, it could be caused by faulty motherboard, and if the problem started happening soon after you swapped it, the motherboard becomes suspect no 1. However, again, can't really assume that's the culprit, cos I don't have enough data. What I know for sure, neither your CPU or GPU are overheating and causing this. Motherboard temp also should not cause this, even if it is higher then expected.
Next move? Grab a house fan, open side panel, set the fan to blow at VRMs (area to the left and above CPU), and see if and how motherboard temps change, and if it helps with pc going off. If it helps, clear sign your machine needs more case fans installed. If it won't help and pc still goes off, source of problem is elsewhere.

Thanks a lot for the help. I will try that. Your solution helped get a idea of whats happening in my pc. Thanks again.

Okay so, after some days of testing i found out that Motherboard temperature sometimes rises and it stays constant sometimes. To be more clear, For example im booting my pc today morning my MB temperature is constant at 28 degrees and i shut it down. And when i boot it like evening it goes up to 55 degrees at idle. So yeah as you see it is difficult for me to even explain my problem. I used my pc yesterday for like 4 hours and the whole time motherboard temperature stayed constant and when i turned on my pc today morning the temperature started rising without even doing anything. When my MB temperature is high, When i restart it it sets off. Any help would be appreciated. And as you said i tried to blow an house fan on the MB but no use.

So what should i do next?
